BODY-PUNCH RESISTANCE DEVELOPER.

Application filed March 12, 1927. Serial No. 174,777.

Anobject of our invention is to provide a mechanism by means of which the human body may be developed to resist blows, such development being particularly desirable in thetorsal regions. 5

Another object is to provide a device of the character stated which is operable by the user and which can be easily regulated by the user to strike a light or heavy blow. A still further object is to provide a machine which may be so adjusted as to strike a blow at any point on the torso of the user.

Still another object is to provide a devel oping machine which is simple in construction, effective in use, and simple to operate.

Other objects, advantages, and features of invention may appear from the accompanying drawing, the subjoined detailed description, and the appended claims.

In the drawing Fig. 1 is a front elevation of our developing machine.

Fig. 2 is a side elevation of our mach ne with parts broken away.

Fig. 3 is a sectional View taken on line- 3, 3, Fig. 1.

Referring more particularly to the drawing:

Our machine comprises a base 1 preferably formed as a grill comprising crossed metal strips 2, certain of the strip 3 are extended beyond the rear of the platform 1 to lend stability to our machine. A pair of arms 4, 4 extend upwardly and rearwardly atan angle from the platform 1, and said arms are secured to the platform at the lower end thereof by riveting, bolting, or the like,

to the platform strips 5, 5. The arms 4, 4 are formed of strips of spring steel of sufficient stiffness to normally remain in a straight line but which may be easily flexed as Wlll be further described.

The upper ends of the strips 4, 4 are bent at right angles to the main face of the arms, as shown at 6, and a padded block 7 is adjustably secured to each of the arms 4 in the following manner:

A strap 8 is secured to the face 6 and a post 9 secured to the block 7 is pivotally secured to the strap 8 and is held in adjusted position by a wing-nut 10, or the like. Thus it will be seen that by loosening the nuts 10 the post 9 may be raised or lowered to adjust the block 7 to strike the point desired. An operating arm 11 is secured to each of the spring arms 4, 4 by means of the plates 12, or the like, said plates being positioned adjacent the lower ends of the spring arms 4, 4, but above the point atwhich they are secured .to the platform 1. A hand grip 13 may be secured to the top of each of the operating arms 11 so that said arms may be more readily grasped by the user. We also provide a brace plate 14 secured to both of the spring arms 4, 4 at the lower ends thereof.

In operation the user stands upon the platform 1 and adjusts the padded blocks 7, 7 to strike the torso at the point desired. By grasping the operating arms 11, 11 and moving them backward and forward 21 vi-' bration is imparted to the spring arms 4, 4. The rapidity with which the operating arms are moved and the distance over which they are moved regulates the amplitude of vibration of the spring arms 4, 4, and determines the force of the blow given by the padded blocks 7, 7.

()ur developer is particularly applicable to the development of boxers or others desiring to increase the resistance of the torsal muscles to blows, and by reason of the'fact that our machine is operated by the user, a more gradual and effective development is secured. The user'may give himself a very severe or a very light blow, as desired.

The spring arms 4, 4 as previously stated are formed of quite stiff spring'material so that a considerable blow can be struck thereby. The spring arms 4, 4 being inclined rearwardly enablethe user to stand upon the platform 1 and to more readily grasp the operating arms 11, 11 while being struck by the blocks 7, 7.

Having described our invent-ion, we claim: 1. A body punch resistance developer comprising a platform, a spring arm rising from the platform, means on said spring armv operable by the user to flex said spring arm, and an impact block on said spring arm, and means to adjust said impact block on the spring arm.

2. A body punch resistance developer comprising a platform, a pair of spring arms secured to said platform and rising there from, an impact block secured to each of said arms, and an operating arm secured to each of the spring arms adjacent the lower end thereof.

3. A body punch resistance developer comprising a platform, a pair of spring arms secured to said platform and rising therefrom,

an impact block secured to each of said arms,

and an operating arm secured to each of the 5. A body punch resistance developer comprising a grill platform, a pair of spring arms secured to said platform and extending upwardly and rea wardly at an angle therefrom, an operating arm secured to each of the springer-ins adjacent the bottom thereof, a padded block, a post to which the block is secured, said post being pivotally secured to the upper end of the spring arm.

In testimony whereof, we'ai'lix our signatures.
